I have several files on my hard drive that are in .avi format. I have Virtual Dub and my questions are:
1) Using V-Dub, does it convert the file to divx?
2) If the .avi quality is a little poor, will using V-Dub to convert it help the quality?
Sorry for the newbie questions. If there is a How To for V-Dub I would love to know if anyone can point me to it. Thanks.

Humm.... there are a few thing to make it clear first.
AVI is just a container format, just like a post box, written the address (Codec) information in a fixed place, and the Audio Video stream are inside.
DivX 3.x/4.x/5.x are name of Codecs, think about it as different method of encoding + compressing the video.
there are also a Divx MP4 format, which function as AVIs, it is a different sort of container.
V-Dub is a tool / interface to let you work with all sorts of Video Audio codec.
I think now your 1st quest. is sloved.
About the 2nd quest. I am sorry, it wont. It will only get worse of equal, cant get better.
Just like you cant make a heavily compressed JPG image back to what it was in BMP.
However, if a better codec is used, it make make your file smaller without visitable difference in Q. |

Some things like noise can be filtered and thus perceived quality can under certain circumstances be better. But it doesn't work on all material and you need to experiment a lot! |
